Complete BorgWarner friction plate set for the Ford 10R80 and GM 10L80 ten-speed, covering all six clutch packs in one 35955KIT module.
If your F-150, Expedition, Navigator, Mustang, Ranger or Bronco is shifting harshly, flaring between gears or slipping on the highway, and the fluid smells burnt, the 10R80 frictions are likely worn. The BorgWarner 35955KIT is the friction module for the Ford 10R80 and 10R100 and the GM 10L80 and 10L90 the two companies co-developed. One box holds the friction plates for all six clutch packs, A through F, from the supplier that makes the OE lining, so the rebuild goes together without hunting for individual plates.
The 10R80 uses four simple planetary gearsets and six clutches to produce ten forward gears. Each gear holds a combination of packs, and the transmission control module shifts by bleeding off one clutch while filling another with a short, closely timed overlap. That makes the unit very sensitive to clutch clearance. As friction lining wears thin, the piston strokes farther, the oncoming clutch catches late, and you feel it as a flare, a shudder or a hard bang the module cannot adapt out. Burnt frictions also shed debris that circulates through the valve body and solenoids, which is why heat-damaged units should be rebuilt promptly.
Ford ten-speeds have well-known valve body and solenoid complaints that mimic clutch wear, so check those before teardown. Our 10R80 3-4 clutch failure guide explains which shifts point to which pack, and the ten-speed valve body symptoms guide covers the hydraulic side. Sonnax also lists worn sealing rings and hub bushings as a major cause of lost clutch pressure in these units, so measure the rings on the input shafts and drums during the rebuild. Burnt fluid plus debris and a slip that will not adapt out mean new frictions.
35955KIT is listed for 2017 and up Ford 10R80 and 10R100 and GM 10L80 and 10L90. That covers 2017-2022 F-150, 2018-2022 Mustang, Expedition and Navigator, 2019-2022 Ranger and 2021-2022 Bronco, plus GM trucks and SUVs with the 10L80. OEM cross-references on the box are 24270200, 24270326, 24270331, HL3Z-7B164-A, HL3Z-7B164-B and HL3Z-7B164-F. Ford and GM both revised these units over the years, so compare the plate count of each pack you remove with the kit before assembly, or send us your year and VIN to check. More Ford ten-speed parts are on our 10R80 collection page, and a GM-titled listing of the same kit is at 10L80 friction clutch module kit.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. It is the friction plates for all six packs only. Steels, seals, sealing rings and the filter are separate.
2017 and up 10R80 and 10R100 units, including 2017-2022 F-150, 2018-2022 Mustang, Expedition and Navigator, 2019-2022 Ranger and 2021-2022 Bronco.
BorgWarner supplies friction elements to the OE line, and the box cross-references Ford HL3Z-7B164 and GM 24270200-series numbers.
Ford 10R80 units take Mercon ULV. GM 10L80 and 10L90 units take Dexron ULV.
Usually a pack's clearance is out of spec, sealing rings were reused or not sized, or the adaptive tables were not reset and relearned.
